I stumbled reading the code fragment and had to consult the manuals (thanks for that). Are there any benefits of 'defined &$maybe_coderef' syntax (over exists or 'CODE' eq ref... or TIMTOWTDI-others)? It triggers 'uninitialized' warning for uninitialized value, but maybe there are not obvious benefits?
